Giant mesenteric lipoma: A case report and a review of the literature

Abstract Mesenteric lipoma is a rare benign tumor of mature fat cells. Although generally asymptomatic, it occasionally causes abdominal pain, ileus, and small bowel volvulus, depending on its location and size. A definitive diagnosis can be made by pathological examination. Ultrasonography and abdominal computed tomography show this lesion as a well-defined, homogenous mass with fat density surrounded by a thin capsule. Because of its rare etiologic origin, we report the case of a 2-year-old male presented with progressive abdominal distension and failure to thrive, found to be caused by a mesenteric lipoma.
